Antique Vienna 3-Weight Regulator

Pendulum is attached to the case

Two sets of coil gong for striking of the quarters and hours 

The key to wind up the weights

This is a 3-weight Vienna regulator made ca.1880. It's called a blind man's clock because of the way it strikes, the "Granne Sonnerie" strike. It'll strike the quarter tone first on a gong and then the hour tone on another gong of different pitch.
